As US soldier is charged for alleged Maduro bets, SEC conducts strikingly low-key probe of futures and prediction markets

• Van Dyke allegedly bet $33,034 on Polymarket starting Dec. 26 on whether the US would remove Maduro by end of January, despite signing nondisclosure agreements about the military operation
• Suspicious March trades included $760 million in oil futures and $2 billion in S&P futures just before Trump's Iran pause announcement, potentially netting traders $40-50 million in profits
• Kalshi recently suspended three politicians for potential insider trading on their own campaigns as regulatory scrutiny intensifies, though proving insider trading in prediction markets remains legally challenging

Summary

Federal prosecutors charged Army officer Gannon Ken Van Dyke with insider trading after he allegedly netted $400,000 trading on classified information about a U.S. military operation targeting Venezuelan President Nicolás Maduro. Van Dyke, who was involved in planning the operation, reportedly invested approximately $33,034 in "yes" positions on Polymarket regarding whether the U.S. would remove Maduro by end of January, violating nondisclosure agreements he had signed.

While the Department of Justice has been vocal about cracking down on suspicious trading in futures and prediction markets, the SEC is conducting a quieter investigation into well-timed, high-dollar trades capitalizing on surprise news developments. SEC Chairman Paul Atkins views potential insider trading as eroding public trust in fair markets.

Key Market Activity:

In March, unusual trading preceded President Trump's Iran policy announcement: 7,200 oil futures contracts ($760 million value) betting on price declines and 6,000 S&P futures contracts ($2 billion notional value) changed hands, potentially generating $40-50 million in profits when oil prices plummeted and stocks surged.

Both major prediction platforms—Polymarket and Kalshi—maintain they enforce strict anti-insider trading rules. Kalshi recently suspended three politicians for potentially using insider information about their own campaigns.

Regulatory Challenges:

Proving insider trading remains difficult beyond "classic" cases involving firsthand access to material non-public information. Recent court precedents have raised prosecution barriers, and legal market intelligence software using "mosaic" information could explain some suspicious-looking trades.

The CFTC, which oversees futures markets, declined to comment on any investigations.
